Best protein i have had this far, all in all.
It has everything i need and it tastes grate, you can use it eaven whit out orginal shakrHonestly, this is the best protein I have had so far. Everything in it is top quality. You can even mix it without the shaker grid, it mixes perfectly just by shaking it, and that is exactly how I like to make it. The Cookies and Cream version has little ''cookie pieces'' in it, so they don''t get stuck in the grid either, because the protein doesn''t clump at all and mixes extremely well.

Best protein, high quality
Very solid product. I’ve been using it for weeks and recovery feels noticeably better. Flavor is not too sweet, which I personally prefer.

Tastiest protein I''ve ever tried
I ordered the Mango Whey hydro isolate protein and was blown away by how easily it dissolves and how good it tastes. With only cold water, it dissolves super quickly and tastes like a smoothy. Makes drinking protein something I look forward to, and crave!

I loved it!
Dissolve quickly and it has an amazing texture. One of the best I tried. For sure I’ll order more. Dulce de leche is a good idea, Prozis!!!

A protein that feels great
I really liked it. It has a good texture, dissolves easily, and is ideal to take after training. A very practical option to supplement your diet and aid muscle recovery. I would definitely buy it again.

Single-dose speculums
Ideal for travel or trying new flavors (or to keep at home as an emergency measure when you run out of protein powder). It dissolves very well, without leaving clumps. The taste and smell are identical to the original cookies.

Excellent product
Tried them for the first time, and I have to say they're excellent! They're very easy to digest, melt quickly, and have no aftertaste. I got the white chocolate ones, and they're delicious.
